From 9f340e80aac2be1018c2b9ab54673293d1b8c1da Mon Sep 17 00:00:00 2001 From: jedarden Date: Sun, 24 May 2026 20:39:25 -0400 Subject: [PATCH] fix(engine): increase spawn radius to allow zone forcing function Previous spawn radius of 15% placed bots only 6 tiles apart on 40x40 grid, causing immediate combat engagement in 2-3 turns. Zone starts at turn 20, so bots should start far enough apart that they cannot reach each other before the zone forces them together. Updated spawn radius from 15% to 60% for 2-player (24 tiles apart) and 18% to 50% for 3+ players. Matches now last 12-35 turns with varied outcomes (draws and eliminations), allowing the zone to serve as the intended forcing function for combat engagement.
